BORNA DE CONEXION DESCRIPClONDESCRIPTION CONNECTION TERMINAL
La invencion se refiere a una borna de conexion, en particular a una borna de conexion electrica para conductores con una gran superficie de seccion transversal.The invention relates to a connection terminal, in particular an electrical connection terminal for conductors with a large cross-sectional area.
Hasta hoy es reducida la cantidad de bornas de conexion que son adecuadas tambien para embornar conductores con una gran superficie de seccion transversal del conductor, en particular una seccion transversal del conductor o una superficie de la seccion transversal del conductor > 35 mm2. Las bornas de conexion conocidas para embornar conductores con una gran superficie de seccion transversal, presentan la mayona de las veces una conexion atornillada. Ademas se conoce tambien una combinacion de una conexion atornillada y una conexion por resorte, en la cual mediante un mecanismo de tornillo se tensa un resorte, que funciona similarmente a un manguito de apriete de una borna atornillada y que aprieta el conductor a aprisionar contra una barra conductora configurada plana. Todas estas conexiones oprimen el conductor a aprisionar la mayona de las veces contra una barra conductora configurada plana. Entonces es facil que se deslice el conductor a aprisionar, con lo que ya no puede garantizarse un aprisionamiento seguro del conductor sobre la barra conductora configurada plana. El documento EP 1 248 318 A2 da a conocer las caractensticas de los preambulos de las reivindicaciones 1 y 2. La invencion tiene por lo tanto como objetivo basico proporcionar una borna de conexion en la que se impida un deslizamiento indeseado del conductor dentro de la borna de conexion y asf pueda garantizarse un aprisionamiento seguro del conductor.Until now, the number of connection terminals that are also suitable for embedding conductors with a large cross-sectional area of the conductor, in particular a cross-section of the conductor or a cross-sectional area of the conductor> 35 mm2, is reduced. The connection terminals known for embedding conductors with a large cross-sectional area, have the majority of the times a screwed connection. In addition, a combination of a screwed connection and a spring connection is also known, in which a spring is tensioned by means of a screw mechanism, which works similarly to a clamping sleeve of a screwed terminal and that presses the conductor to clamp against a flat configured conductive bar. All these connections press the driver to pinch the majority of the time against a flat configured busbar. Then it is easy for the driver to slide in, so that a safe imprisonment of the driver on the flat configured busbar can no longer be guaranteed. EP 1 248 318 A2 discloses the features of the preambles of claims 1 and 2. The invention therefore has as a basic objective to provide a connection terminal in which an unwanted sliding of the conductor within the terminal is prevented. of connection and thus a safe imprisonment of the driver can be guaranteed.
En una borna de conexion del tipo citado mas en detalle al principio se logra este objetivo segun la invencion presentando la borna de conexion una carcasa, un cajetm de embornado dispuesto en la carcasa, en el que puede introducirse un conductor a embornar y al menos un resorte de presion que penetra en el cajetm de embornado para embornar el conductor introducido en el cajetm de embornado, presentando el cajetm de embornado una pared del fondo y dos paredes laterales enfrentadas, que se extienden partiendo de la pared del fondo, que configuran un canal de grna del conductor, presentando el canal de grna del conductor a lo largo de su direccion longitudinal, al menos en determinadas zonas, una seccion transversal que se estrecha continuamente en direccion hacia la pared del fondo.In a connection terminal of the type mentioned in more detail at the beginning, this objective is achieved according to the invention by presenting the connection terminal a housing, a embedding box arranged in the housing, into which a conductor to be connected and at least one pressure spring that penetrates the embedding cage to embed the conductor inserted in the embedding cage, the embedding cage presenting a bottom wall and two facing side walls, which extend from the back wall, which form a channel The driver's channel, the driver's channel along its longitudinal direction, at least in certain areas, has a cross-section that continuously narrows in the direction of the bottom wall.
En las reivindicaciones secundarias se indican variantes convenientes y perfeccionamientos ventajosos de la invencion.Suitable variants and advantageous improvements of the invention are indicated in the secondary claims.
La borna de conexion de acuerdo con la invencion se caracteriza porque la barra conductora esta configurada ahora en forma de un cajetm de embornado, que mediante una pared del fondo y mediante dos paredes laterales, que se extienden lateralmente partiendo de la pared del fondo, configura un canal de grna del conductor, en el que es posible una conduccion definida del conductor y en particular puede impedirse un indeseado desplazamiento lateral del conductor desde una posicion de aprisionamiento. El canal de grna del conductor se caracteriza ademas porque el mismo presenta a lo largo de su direccion longitudinal, al menos en determinadas zonas, una seccion transversal que se estrecha continuamente en direccion hacia la pared del fondo. La seccion transversal que se estrecha continuamente constituye un centrado para el conductor a aprisionar en el canal de grna del conductor, con lo que el conductor puede sujetarse en el canal de grna del conductor de manera segura frente al resbalamiento. La seccion transversal que se estrecha no se extiende preferentemente por toda la altura del cajetm de embornado, sino que esta realizada en la zona inferior del cajetm de embornado, allf donde se ha introducido el conductor. En la zona superior del cajetm de embornado, donde tambien esta apoyado el resorte de presion en el cajetm de embornado, estan dispuestas las paredes laterales enfrentadas discurriendo en paralelo una a otra. La seccion transversal del canal de grna del conductor que se estrecha continuamente esta configurada entonces tal que el movimiento de la patilla de sujecion del resorte de presion configurado como resorte de patillas no queda limitado por la seccion transversal que se estrecha. La borna de conexion se caracteriza ademas por una forma constructiva compacta, en la que pueden conectarse conductores con distintas secciones transversales del conductor.The connection terminal according to the invention is characterized in that the conductive bar is now configured in the form of a terminal block, which by means of a bottom wall and by two side walls, which extend laterally starting from the bottom wall, configures a channel of the driver's channel, in which a defined conduction of the conductor is possible and in particular an undesired lateral displacement of the conductor from a clamping position can be prevented. The channel of channel of the conductor is further characterized in that it has along its longitudinal direction, at least in certain areas, a cross section that continuously narrows towards the bottom wall. The cross section that narrows continuously constitutes a centering for the conductor to be imprisoned in the conductor's channel, so that the conductor can be securely fastened to the conductor's channel in the face of slipping. The narrowing cross-section does not preferably extend over the entire height of the embedding cage, but is made in the lower part of the embedding cage, where the conductor has been introduced. In the upper area of the embedding box, where the pressure spring is also supported on the embedding box, the facing side walls are arranged running parallel to each other. The cross section of the continuously narrowing conductor channel is then configured such that the movement of the clamp spring pin configured as a pin spring is not limited by the cross section that narrows. The connection terminal is also characterized by a compact construction form, in which conductors with different conductor cross-sections can be connected.
La seccion transversal del canal de grna del conductor que se estrecha esta configurada preferentemente con una forma de V o una combinacion de una forma de U y una forma de V. La seccion transversal que se estrecha se configura preferentemente tal que ambas paredes laterales presentan cada una al menos un bisel, que converge con el respectivo bisel de la pared lateral opuesta. Cuando se trata de una combinacion de una forma de U y una forma de V, no chocan entre sf los biseles enfrentados de ambas paredes laterales en la zona de la pared del fondo del cajetm de embornado, sino que los mismos estan distanciados entre sf tambien en la zona de la pared del fondo, con lo que la pared del fondo esta configurada lisa o plana entre ambos biseles enfrentados de la pared lateral, pero la pared del fondo tiene una anchura reducida respecto a zonas en las que ambas paredes laterales discurren paralelas entre sf. Por el contrario en la forma de V chocan entre sf ambos biseles de las paredes laterales enfrentadas en la zona de la pared del fondo, con lo que la anchura de la pared del fondo queda reducida aqrn a un mmimo.The cross section of the narrowing conductor channel is preferably configured with a V-shape or a combination of a U-shape and a V-shape. The narrowing cross-section is preferably configured such that both side walls have each at least one bevel, which converges with the respective bevel of the opposite side wall. When it is a combination of a U shape and a V shape, the opposite bevels of both side walls do not collide with each other in the area of the bottom wall of the embedding box, but they are also spaced apart from each other as well. in the area of the bottom wall, whereby the bottom wall is set flat or flat between both bevels facing the side wall, but the bottom wall is reduced in width from areas where both side walls run parallel between sf. On the contrary, in the V-shape, both bevels of the side walls facing each other in the area of the bottom wall collide with each other, whereby the width of the bottom wall is reduced here to a minimum.
La seccion transversal que se estrecha continuamente del canal de grna del conductor puede estar constituida entonces por al menos dos estampados enfrentados, configurados en una zona de transicionThe cross section that continuously narrows the conductor's channel can then be constituted by at least two facing patterns, configured in a transition zone

entre una pared lateral y la pared del fondo. Los estampados estan configurados en la direccion del espacio interior del canal de grna del conductor. Un estampado se extiende en cada caso por una zona de la pared lateral contigua a la pared del fondo y una zona de la pared del fondo. Los estampados pueden estar configurados por ejemplo triangulares o tambien como protuberancia en forma de un casquete esferico. Por cada pared lateral puede estar configurado tambien mas de un estampado, estando distanciados entonces los estampados de una pared lateral entre sf, no estrechandose en la zona entre dos estampados configurados en una pared lateral la seccion transversal del canal de grna del conductor, sino presentando una seccion transversal con forma rectangular, con lo que en la zona de la seccion transversal con forma rectangular el extremo libre del resorte de presion puede moverse libremente sin tocar ninguno de los estampados.between a side wall and the back wall. The patterns are configured in the direction of the interior space of the driver's channel. A pattern extends in each case through an area of the side wall adjacent to the bottom wall and an area of the bottom wall. The patterns can be configured for example triangular or also as a protuberance in the form of a spherical cap. For each side wall, more than one pattern can also be configured, then the patterns of a side wall are spaced apart from each other, the cross-section of the driver's channel being not narrowed in the area between two patterns configured on a side wall, but presenting a cross section with a rectangular shape, whereby in the area of the cross section with a rectangular shape the free end of the pressure spring can move freely without touching any of the patterns.
Alternativamente a la configuracion de la seccion transversal que se estrecha mediante estampados, es posible ademas que la seccion transversal del canal de grna del conductor que se estrecha continuamente se extienda por toda la longitud del canal de grna del conductor, presentando las paredes laterales respectivos segmentos de pared lateral contiguos a la pared del fondo, que estan configurados inclinados hacia la pared del fondo, presentando los segmentos de pared lateral correspondientes a las paredes laterales y que se encuentran contiguos a la pared del fondo, al menos dos escotaduras enfrentadas entre sf, en las que puede introducirse un extremo libre de una patilla de sujecion del resorte de presion. Cuando se extiende la seccion transversal del canal de grna del conductor que se estrecha continuamente por toda la longitud del canal de grna del conductor, puede impedirse con seguridad que resbale el conductor en el canal de grna del conductor. Las paredes laterales estan aqrn divididas en dos segmentos, visto en la direccion de la pared del fondo, estando colocados oblicuos los segmentos de pared lateral proximos a la pared del fondo o bien estando inclinados hacia la pared del fondo, con lo que estos segmentos de pared lateral de ambas paredes laterales pueden converger uno hacia otro. El segmento de pared lateral correspondiente a una pared lateral que esta alejado de la pared del fondo, esta configurado por el contrario a un angulo de esencialmente 90° respecto a la pared del fondo, con lo que estos segmentos de pared lateral de ambas paredes laterales enfrentadas estan configurados paralelos entre sf En la zona de giro de la patilla de sujecion del resorte de presion esta configurada en ambos segmentos de pared lateral constituidos inclinados en cada caso una escotadura, estando enfrentadas las escotaduras de ambos segmentos de pared lateral. Las escotaduras hacen posible que el extremo libre del resorte de presion, cuando se encuentra proximo a la pared del fondo, lo cual es el caso en particular cuando no esta aprisionado el conductor o al aprisionar conductores con una superficie del seccion transversal muy pequena, pueda introducirse allf. El extremo libre del resorte de presion no tiene asf que adaptarse a la forma de seccion transversal que se estrecha del canal de grna del conductor, sino que puede configurar una superficie recta. Si el extremo libre de la patilla de presion se estrechase o redujese igualmente hacia la punta del extremo libre, podna configurarse lateralmente un intersticio entre el canal de grna del conductor y la patilla de presion, dentro del cual podnan introducirse hilos individuales de un conductor, con lo que ya no podna garantizarse una toma de contacto segura. El extremo libre de la patilla de sujecion del resorte de presion presenta asf en este caso otra forma de seccion transversal distinta de la del canal de grna del conductor. Alternativamente a las escotaduras, puede estar configurada en las paredes laterales en cada caso al menos una protuberancia, que configura el canal de grna del conductor en esta zona tan ancho que una superficie recta en el extremo libre de la patilla de sujecion del resorte de presion puede introducirse en las protuberancias y con ello el resorte de presion, pese a que la seccion transversal esta configurada tal que se estrecha en toda la longitud del canal de grna del conductor, puede realizar sin obstaculos un movimiento de giro dentro del canal de grna del conductor.Alternatively to the configuration of the cross section that is narrowed by means of stamping, it is also possible that the cross section of the conductor channel which is continuously narrowed extends over the entire length of the conductor channel, presenting the respective side walls segments side wall adjacent to the bottom wall, which are configured inclined towards the bottom wall, presenting the side wall segments corresponding to the side walls and which are adjacent to the bottom wall, at least two recesses facing each other, in which a free end of a clamping pin of the pressure spring can be introduced. When the cross section of the driver's channel is extended, which continuously narrows along the entire length of the driver's channel, it can be safely prevented from slipping the conductor into the conductor's channel. The side walls are here divided into two segments, seen in the direction of the bottom wall, the side wall segments near the bottom wall being obliquely positioned or inclined towards the bottom wall, whereby these segments of Side wall of both side walls can converge towards each other. The side wall segment corresponding to a side wall that is away from the bottom wall, is instead set at an angle of essentially 90 ° with respect to the bottom wall, whereby these side wall segments of both side walls facing each other, they are configured parallel to each other. In the area of rotation of the clamping pin of the pressure spring, a recess is formed in both side wall segments constituted in each case, the recesses of both side wall segments facing each other. The recesses make it possible for the free end of the pressure spring, when it is close to the bottom wall, which is the case in particular when the conductor is not trapped or when clamping conductors with a very small cross-sectional area, can enter there. The free end of the pressure spring does not have to adapt to the narrow cross-sectional shape of the driver's channel, but it can form a straight surface. If the free end of the pressure pin is narrowed or reduced equally towards the tip of the free end, a gap may be laterally configured between the driver's channel and the pressure pin, into which individual wires of a conductor may be introduced, which can no longer guarantee a safe contact. The free end of the clamping pin of the pressure spring thus has, in this case, another form of cross-section other than that of the driver's channel. Alternatively to the recesses, at least one protrusion can be configured on the side walls in each case, which configures the driver's channel in this area so wide that a straight surface at the free end of the clamping pin of the pressure spring it can be introduced into the protuberances and with it the pressure spring, although the cross-section is configured such that it narrows along the entire length of the driver's channel, it can make a turning movement within the channel of the channel driver.
Para facilitar la introduccion de un conductor en el canal de grna del conductor y con ello tambien en la borna de conexion, esta previsto ademas preferentemente que en la direccion de insercion del conductor antes del canal de grna del conductor, en el cajetm de embornado este dispuesto un segmento de grna que penetra en una abertura de grna del conductor de la carcasa, presentando el segmento de grna con preferencia una seccion transversal que se estrecha. La seccion transversal que se estrecha del segmento de grna puede estar constituida por ejemplo por una forma de V o una combinacion de una forma de U y una forma de V.In order to facilitate the introduction of a conductor in the conductor's channel of grading and with it also in the connection terminal, it is also preferably provided that in the direction of insertion of the conductor before the conductor's channel of grating, in the embedding box this an array segment that penetrates a slot opening of the housing conductor is arranged, the core segment preferably having a cross section that narrows. The narrowing cross-section of the crane segment can be constituted for example by a V-shape or a combination of a U-shape and a V-shape.
La borna de conexion puede estar configurada con preferencia como una borna de carril, que esta encajada sobre un carril de soporte, presentando la carcasa para ello con preferencia un pie de retencion para fijar la borna de conexion sobre un carril de soporte. El pie de retencion esta configurado preferentemente formando una sola pieza con la carcasa.The connection terminal may preferably be configured as a rail terminal, which is fitted on a support rail, the housing thus preferably having a retaining foot for fixing the connection terminal on a support rail. The retention foot is preferably configured in a single piece with the housing.
A continuacion se describira la invencion mas en detalle con referencia a los dibujos adjuntos, en base a formas de realizacion preferidas.The invention will be described in more detail below with reference to the attached drawings, based on preferred embodiments.

Las figuras 1 y 2 muestran una primera forma de realizacion de una borna de conexion con un cajetm de embornado 1, en el que estan posicionados dos resortes de presion 2, que aqrn estan configurados como paquetes de resortes de presion compuestos por varios elementos de resorte de presion. En un cajetm de embornado 1 pueden aqrn por lo tanto embornarse a la vez dos conductores 19, 20 sobre los dos resortes de presion 2, como se muestra en la figura 8. Los resortes de presion 2 estan configurados aqrn como resortes de patilla. Pero alternativamente pueden estar configurados los mismos tambien como resortes de jaula.Figures 1 and 2 show a first embodiment of a connection terminal with a terminal block 1, in which two pressure springs 2 are positioned, which are still configured as pressure spring packages composed of several spring elements of pressure Therefore, two conductors 19, 20 on the two pressure springs 2, as shown in Fig. 8, can therefore be connected in a casing box 1, as shown in Figure 8. The pressure springs 2 are configured here as pin springs. But alternatively they can also be configured as cage springs.
El cajetm de embornado 1 presenta una pared del fondo 3 y dos paredes laterales 4a, 4b enfrentadas que se extienden partiendo de la pared del fondo 3. La pared del fondo 3 y las dos paredes laterales 4a, 4b forman un canal de grna del conductor 5, que se extiende por toda la longitud del cajetm de embornado 1. En el canal de grna del conductor 5 esta configurada una abertura 6, en la cual puede fijarse una pared separadora, que se extiende entonces dentro del cajetm de embornado 1 partiendo de la pared del fondo 3 hacia arriba por el espacio interior dentro del cajetm de embornado 1. La pared separadora divide el canal de grna del conductor 5 en dos zonas, en las que pueden introducirse respectivos conductores 19, 20, pudiendo insertarse los conductores 19, 20 en el canal de grna del conductor 5 en cada caso a tal profundidad que los mismos chocan con su superficie frontal contra la pared separadora.The embedding box 1 has a bottom wall 3 and two side walls 4a, 4b facing each other extending from the bottom wall 3. The bottom wall 3 and the two side walls 4a, 4b form a driver's channel 5, which extends over the entire length of the embedding cage 1. In the driver's channel 5 an opening 6 is configured, in which a separating wall can be fixed, which then extends into the embedding cage 1 starting from the bottom wall 3 upwards through the interior space inside the embedding box 1. The separating wall divides the channel of the conductor 5 into two zones, in which respective conductors 19, 20 can be introduced, the conductors 19 being able to be inserted, 20 in the channel of the conductor 5 in each case at such depth that they collide with its front surface against the separating wall.
El canal de grna del conductor 5 presenta a lo largo de su direccion longitudinal, en determinadas zonas, una seccion transversal que se estrecha continuamente en direccion hacia la pared del fondo 3, configurandose en la zona de la seccion transversal del canal de grna del conductor 5 que se estrecha continuamente una combinacion de una forma de U y una forma de V. Esto significa que allf donde las paredes laterales 4a, 4b estan unidas con la pared del fondo 3, presentan aun las paredes laterales 4a, 4b una distancia entre sf, con lo que la seccion transversal del canal de grna del conductor 5 no esta configurada en punta, sino que presenta la forma de un tronco del cono cortado longitudinalmente. Esto se configura aqrn mediante en cada caso dos estampados 7a, 7b enfrentados entre sf, configurados en una zona de transicion entre una pared lateral 4a, 4b y la pared del fondo 3. Los estampados 7a, 7b estan configurados en la direccion del espacio interior del canal de grna del conductor 5. Un estampado 7a, 7b se extiende en cada caso por una zona de la pared lateral 4a, 4b contigua a la pared del fondo 3 y una zona de la pared del fondo 3. Los estampados 7a, 7b estan configurados aqrn con forma triangular. Por cada pared lateral 4a, 4b estan configurados dos estampados 7a, 7b, estando distanciados entre sf los estampados 7a, 7b de una pared lateral 4a, 4b en la direccion longitudinal del canal de grna del conductor 5. La distancia a esta configurada suficientemente grande para que la misma configure una zona de giro para el extremo libre 8 de la patilla de sujecion 10 del resorte de presion 2. En la zona 9 entre dos estampados 7a, 7b configurados en una pared lateral 4a, 4b la seccion transversal del canal de grna del conductor 5 no esta configurada estrechandose, sino que el canal de grna del conductor 5 presenta una seccion transversal con forma rectangular, con lo que en la zona 9 de la seccion transversal con forma rectangular del canal de grna del conductor 5 el extremo libre 8 del resorte de presion 2 puede moverse libremente, sin tocar ninguno de los estampados 7a, 7b. El extremo libre 8 de la patilla de sujecion 10 puede asf "trabajar" entre dos estampados 7a, 7b de una pared lateral 4a, 4b.The channel of channel of the conductor 5 presents along its longitudinal direction, in certain areas, a cross-section that continuously narrows in the direction towards the bottom wall 3, being configured in the area of the cross-section of the channel of conduit of the conductor 5 that a combination of a U-shape and a V-shape is continuously narrowed. This means that where the side walls 4a, 4b are connected to the bottom wall 3, the side walls 4a, 4b still have a distance between each other. , whereby the cross section of the channel of the conductor 5 is not configured in tip, but has the shape of a longitudinally cut cone trunk.
